Features & Benefits
A compressor’s value extends beyond its rated capacity. The P700 combines high-capacity, oil-free centrifugal compression with flexible one-, two-, and three-stage configurations, advanced controls, and proven component designs to help your team maximize efficiency, simplify operation, and support reliable long-term performance.
Confidence for Critical Air Demands
The Polaris P700 is engineered to deliver ISO 8573-1 Class 0 oil-free air with the reliability and efficiency required for demanding industrial applications.
Its oil-free air path helps protect processes from compressor oil contamination, while integrated monitoring and control capabilities help operators maintain visibility into compressor performance and condition.
Optimized Design, Efficient Operation
Polaris compressors combine optimized aerodynamics, efficient intercooling, and custom-designed impellers to reduce power requirements and optimize airflow.
Mechanically superior bearings and adjustable inlet guide vanes further support efficient operation by reducing power consumption and responding to changing plant conditions and air demand.
Designed with Service Access in Mind
The horizontally split gear case provides technicians with convenient access to internal components for inspection and service, while the removable airend simplifies maintenance and replacement to help minimize downtime. Straight-through intercooler tubes allow for easier periodic cleaning, and the Regulus® control system helps operators monitor and optimize compressor performance.
These design choices support a practical maintenance strategy for equipment your facility depends on.

Insights & Resources
Beyond the Price Tag: The Long-Term Cost of Compressed Air
Compressed air is one of the most widely used utilities in industrial operations, and one of the most expensive. While the upfront cost of a compressor often gets the spotlight, it’s only a small part of the total cost of ownership. The real expenses come from energy consumption, system inefficiencies, maintenance practices, consumables, and downtime.
Steel Manufacturer Achieves $40K Annual Savings with Centrifugal Compressor Upgrade
In stainless steel production, uninterrupted uptime isn’t just a target; it’s critical. From powering automation and actuators to supporting cooling and descaling systems, compressed air plays a crucial role in ensuring every part of the mill operates at peak performance.
What Can Oil-Free Air Compressors do for Your Plant?
Across industries, plant operators face growing pressure to reduce operating costs, protect product quality, and meet stringent environmental standards. One of the most effective ways to meet all three goals is by integrating ISO 8573-1 Class 0 certified oil-free air compressors into your compressed air system.
